How the configurator picks the equipment
It starts from the total number of users (desk phones, cordless handsets and app users) and the analog lines you want to keep. Of the Grandstream UCM PBXs that can handle the load, it picks the option with the lowest total price, counting any gateways or ATA adapters needed when the PBX's own analog ports aren't enough.

What else goes on the list
- Desk phones: one model for all desks, plus large-display phones with BLF keys for managers or reception.
- Cordless phones: DECT handsets with one base station for every 5 handsets. For large buildings or several floors, coverage is planned on site.
- PoE switch: one port for each desk phone and each DECT base station.
- SIP trunk: not sold in the shop; you get it from your operator. The configurator tells you how many channels to ask for.
Prices are the current shop prices, VAT included. For a small office, see the ready-made bundles too.
Frequently asked questions
Which PBX do I need for 10, 20 or 50 users?
The Grandstream UCM6300A covers all of these: up to 250 users and 50 concurrent calls. Pick a model with FXO/FXS ports (UCM6301, UCM6302A, UCM6304A) only if you want to keep analog lines or connect a fax or an analog door phone.
Can I keep my current phone numbers?
Yes. Existing analog lines plug into the PBX's FXO ports or into an FXO gateway. If you move to a SIP trunk, the numbers can be ported to the operator that provides the trunk.
Where do I get the SIP trunk and how many channels do I need?
The SIP trunk comes from your telephony operator. As a rule of thumb, one channel for every 3–4 users is enough for a regular office; a call centre needs more. The configurator shows an indicative number of channels.
Do I need a PoE switch?
The phones in the configurator are powered over the network cable (PoE), so you don't need a power adapter at every desk. If you already have a PoE switch with free ports, untick the option and the switch is left out.
Can staff answer calls on a mobile or laptop?
Yes, with the Grandstream Wave app, which is free and runs on Android, iOS and in the browser. Users who only use the app don't need a physical phone; enter them under “Users on the app only”.
Do you also install it?
Yes, on request: we install and configure the PBX, the phones and the trunk. The configurator list contains the equipment only; for installation, ask for a quote using the button under the list.
